- Neither result is too astounding, but what I am looking for is an
- analysis of fatalities versus car size for the SAME circumstances.
- (i.e. all pole impacts below 20 mph, 20-45 mph, >45 mph) It doesn't
- take a rocket scientist to take every accident recorded by the history
- of man and analyze it by size, driver age, or whatever else fits into
- the little data fields on the accident report. If you ever look at
- the standard accident report form, you will see what I mean.
-
- More GIGO. Draw whatever conclusions your political agenda desires.
